Flow Connectors connect different Nodes and Node Properties. Flow Connectors can be connected from a Node or Node Property with an Output Flow Socket to a Node or Node Property with an Input Flow Socket.
Execution Flow Connectors
Execution Flow Connectors indicate how the sequence of execution should take place in a workflow. These connectors are represented by dark blue lines and usually connect Node Headers together.
While most Nodes have a single Output Execution Flow Socket, Nodes that permit decision-based branching such as If and Splitter have multiple output Flow Sockets. In this scenario, the Flow Socket is coupled with a label naming the Execution Output and appears below the Node Header
Note that Flowgear does not parallelise execution of Nodes in a Workflow and therefore it is not possible to connect more than one Execution Flow Connector to the Execution Output Socket of a Node.
Data Flow Connectors
Data Flow Connectors indicate how the data flow should take place in a workflow. Unlike most workflow design environments, Flowgear enables you to visually define execution flows. These Flow Connectors connect Node Properties together.
Working with Flow Connectors
By Dragging (preferred)
Drag from a Node or Output Flow Socket to an Input Flow Socket.
Click an Output Flow Socket, then click an Input Flow Socket.
Use this methods when the source and targets are too far apart to be visible on the Design Canvas together.
Once placed, Flow Connectors can can be dragged to a new target - drag on the Flow Connector to move it to another target Property or Execution Input
To remove a Flow Connector, drag it off it's target and release the mouse button.
When the Nodes connected by a Flow Connector are far apart on the Workflow, the Flow Connector is wormholed. In this state, each end of the Flow Connectors render as a wireless icon. Selecting the wormholed Flow Connector or clicking it's Flow Socket causes the full Flow Connector to display.
